This standard applies to switching devices, interrupters, and interrupter switches (as defined in IEEE Std C37.100-1992) for alternating current, rated above 1000 volts and used indoors, outdoors, or in enclosures for which a switching rating is to be assigned.While this standard covers the basic requirements of interrupter switches used indoors, outdoors, and in enclosures, other standards such as IEEE Std C37.20.2-1993, IEEE Std C37.20.3-1987, IEEE Std C37.20.4-1996, IEEE Std C37.71-1984, and… read more IEEE PC37.73 (D.9, 1997) also contain requirements for switches used in enclosures. This standard does not apply to load-break separable insulated connectors, which are covered by IEEE Std 386-1995 [B7]. This standard also does not apply to circuit-breakers, circuit-switchers, or reclosers. read less

This document describes guidelines for online monitoring of large synchronous generators with ratings of 10 MVA and above. The scope includes generators with salient-pole rotors as well as generators with cylindrical rotors. This standard also provides basic information on the various online monitoring techniques described as well as recommended threshold values for initiating a remedial or compensating action, whenever those values are typical within the power generation industry. This… read more standard does not cover those instruments that are clearly associated with the protection scheme of the generator, such as: differential, out-of-step, over/under frequency, and so forth. read less

This guide provides information of special relevance to planning, design, testing, installation, operation and maintenance of gas-insulated substations (GISs) and equipment. This guide is intended to supplement IEEE Std C37.122(TM). This guide is applicable to all GISs above 52 kV. However, the importance of topics covered varies with application category. For example, the issues related to advanced field test techniques and very fast transients (VFT) are of particular interest for extra-high voltage (EHV) GISs.
